Another object of the invention is the provision of a handle of novelconstruction especially adapted for obtaining a concealed fastening.

The nature of the invention and its dis tinguishing features andadvantages will appear when the following specification is read inconnection with the accompanying drawing, in which F igure 1 is a sideelevation showing a portion of'a metallic door with push and pullhandles applied thereto in accordance with the present invention.

It is to be understood that the fastening means of the present inventionmay be diversely applied for attaching one, two or three handles, andthat the illustrated embodiments are by way of example only. Furthermorewhile the fastening means is shown in connection with handles, it is tobe understood that it maybe employed in conjunction with other elementsin which a concealed fastening is desirable.

In the illustrated embodiment of the invention shown in Figs. 1 to 6inclusive, a metallic door 10 is equipped with a pull handle 11 on oneside of the doorand two pushhandles 12 on the opposite side of the dotif"cured in" pla'ce similar devices or means 13 which will includestructural features on the handles as well as structural features on .tor i i the na'nnerpresently to be described. A.

tlireatl cl ext nsion 14' fof1- the handle 11 'eX- 7 tends throughanjopening 15 1n one ofthe sections of the door, and connectedto theextension 14 1sconnect ng elemeiitj 16' having' a threaded bore 17'which" accommodates fltherextension 14. 'The. element 16 is providedwith a groove 18 at one end thereof which provides a head19 andshoulders 20. The end of theelement 16 having the head and shouldersextends through an opening 21 in a section of the door, the said opening21 being in axial alignment with the opening 15. The head and shouldersof the element 16 are disposed beyond the outer face of the doorsection. Each push handle 12 is of novel construction and consists of agrip section 22 and ends 23 disposed at an 'jThe2pull and push handlesarc'se- [Lac l i device' lig con'sfists' and functions in i angle to thegrip section 22. .Each end23 is provided with an opening 24, and arecess which is larger than the opening 24 to provide an internalshoulder 26. One end 23 of ahandle 12 accommodates the head andshoulders by virtue of the opening 24 and recess 25' therein in a mannerin which the head 19 will bedisposed in the recess 25, and the shoulder26 Will be disposed between the shoulders 20 as shown most clearly inFig. 4, I A fastening element such as a screw 27 is screwed home in athreaded bore 28 in the end 23- so that the inner. end of the screw 27will be disposed in the groove 18 between the shoulders 20, after whichthe screw is cut oil as indicated in Fig. 4. Thus one end of one pushhandle is eecured; The opposite end 23 being similarly constructed, iscapable of accommodating the head 29 of a fastening element such as thescrew 30. The screw 30 is applied to a section of the door with the headthereof spaced from the section of the door, as shown most clearly inFig. 7. The

employment of the, screw in the manner stated presents ahead andshoulder construction similar to that presented bythe connecting element17. Bythe employment of a second screw 27 connection of the handle endmay be made to the screw 30 to complete the fastening.

In the illustrated embodiment three handies are shown attached to thedoor 10, one a pull handle 11 and two push handles 12. The fasteningbetween the opposite ends of the handle 11 and ends respectively of thehandles 12 are identical, and so are the fastenings of the opposite endsof the handles 12 to the door 10. If desired a single handle of the typeof handle 12 may be secured in place in conjunction With two screws likethe screw 30; the use of a connecting element such as the type ofconnecting element 16 being obviated.

It is to he understood that the invention is not restricted to theprecise arrangement of parts shown and described, as details ofconstruction may he modified and rearranged without departing from thespirit of the invention, the scope of which is limited only by the termsof the appended claims.

I claim:

1. The combination on a door, of a pull connecting; element having athreaded bore in one end thereof, a groove in the other end, shouldersand a head at said grooved end, the threaded bore adapted to receive athreaded extension on one of the handles, and the head adapted to bereceived in a recess in the other handle, the last mentioned handlehaving a portion engageable between said shoulders, and a member carriedby said last mentioned handle and extending into said groove. i t
